Storm Water Pollution Protection PlansCDG staff have many years of experience in the development of Storm Water Pollution Prevention Plans (SWPPP) for compliance of state, federal, and tribal land requirements for storm water permitting. CDG’s principal was instrumental of the development of the first ‘ADOT Erosion and Pollution Control Manual’ for the Arizona Department of Transportation. This manual (since updated) is still in use today and provides statewide guidance on the General Permit requirements and implementation of erosion control Best Management Practices (BMP) and State and Federal compliance strategies.

CDG landscape architects and designers have successfully designed over 100 miles of temporary erosion control plans and developed numerous large scale SWPPP’s for construction projects that included water quality monitoring and construction inspections. CDG has 3 certified Erosion Control Coordinators on staff ready to assist on all levels of SWPPP planning and design for all types of construction projects.

Native Plant InventoryNative plant protection and ecosystem restoration have become major components of transportation corridor planning and site development. CDG professionals have conducted numerous large scale native plant inventories and salvage plan designs for major transportation corridors throughout the State of Arizona. CDG manages all phases of native plant identification, salvage and desert ecosystem restoration, relying on the latest GPS and CADD technologies to ensure accuracy and completeness.
